Question 1133697
This is not a complete solution.  You should have a question but you did not state one.  Kwame might want to know how many vans and how many cars he could wash in a week.


2 hours for 1 van
1 hour for 1 car
14 hours available
minimum of 2 vans
number of cars = AT LEAST 2 times number of vans


c, number of cars
v, number of vans


{{{system(v>=2,c>=2v,2v+c<=14)}}}
